(No model.)Patented inEngland November 19. 1889. 110.155.529: in France December 5,1889,1To. 202.409; in Belgium December 6, 1889.1To. 88,745; in GermanyDecember 6,1889,No. 52,652, and in Austria-Hungary March 20, 1890, No.52,491 and No. 9.948.

To au whom it may concern.-

Be it known that WILLIAM THOMAS WALK- ER, deceased, a British subject,late of Bishopswood, Highgate, in the county of Middlesex, England, didin his lifetime invent certain new and useful Improvements in Stills o1'Apparatus for Submitting Liquids to the Action of Vapors or Gases, (forwhich Letters Patent have been granted in the following Io countries,viz: Great Britain, dated November 19, 1389, No. 18,529; France, datedDecember 5, 1889. No. 202,409; Belgium, dated December 6,1889,No.88,745;Germany, dated December 6, 1889, No. 52,652; Austria-Hungary, dated I5March 20, 1890, No. 52,491 and No. 9,948), of which the following is aspecification. This invention has for its object to provide stills orapparatus for submitting liquids to the action of vapors or gases withmeans 2o whereby the vapors or gases and the liquids are caused,in agiven sized apparatus to have a much larger or more extended surface of,contact than in such stills or apparatus as hitherto constructed, afurther advantage being that the rush or pulsation of the vapor or gashitherto experienced isobviated.

The said invention relates to those stills or apparatus in which theliquids are passed into trays or shallow chambers the vapor or gas 3obeing admitted thereto under a hood from which it passes into theliquid, and is animprovement on apparatus of the kind shown anddescribed in my application for Letters Patent of even date herewith,Serial No.

I will describe the said invention with reference t0 the accompanying,drawings which show enough of a still or like apparatus to illustratethe application of lthis invention 4o thereto.

Figure 1 is a plan of the interior of one of the tiers or trays, andFigs. 2and 3 beinghalf sections respectively taken on the line 1.2 andthe line 3.4 of Fig. 1.

According to this invention there is substituted for the hood hithertoused -an oblong or inverted trough-like chamber A extending across thelower surface or floor of each of the trays B of which the still isformed the said oblohg ortrough-like chamber A receiv- 5o ing the vaporor gas from an inlet Ctherefor, which is prt'eerably lengthened in plan(instead of being circular) so as to follow somewhat the, shape `of theinverted oblong or trough-like'chamber A which is closed at 55 its endsa o', and has communicating with it a number of inverted trough-likebranches A2 A2 also closed at their-ends 0.2 a2, these branchesextending out at right angles (or ap proximately so) from the invertedoblong 6o trough-like chamberA toward the periphery or sides of the'tray B. These branches serve to 'distribute very effectually the vaporsor gasses through and over theliquid on the door of the tray.

The lower edge of any desired parts of the chamber A and branches A2 areformed with serrations or teeth d or perforations or thev likeconstituting passage ways for the vapor or gas to pass through incontact with the 7o liquid all over the floor of the tray, the saidliquid flowing from the inlet E to the outlet F as indicated by thearrows. It is generally preferred to provide only the branches A2 withsuch serrations or the like. Between the branches A2 yand extendingupward from the floor of the tray B are walls or plates G which form oneither side of the inverted oblong or trough-like chamber Aand along thesides of the branches A2 circuitous passage for the 8o liquid undertreatment.

rlhe still or apparatus may consist of any number of these chambersarranged one above the other with communicating passages for the liquidsandv vapors or gases from chamber to chamber as is customary and asindicated in the drawings. The chambers A with the branches A2 may beraised and lowered by the central vertical shaft after the mannerdescribed in the specification of the 9o application for Letters Patentmade by me of even date herewith, Serial No. 494,309.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, I- declarethat what I claim is 1. In stills or apparatus for submitting liquids tothe action of vapors or gases an i11- said branches, substantially ashereinbefore described.

In testimony whereof I, MARCELLUS BAI- 15 LEY, administrator ot theestate of WILLIAM THOMAS WALKER, deceased, hereunto set my hand this21st day of December, 1893.
